Haynes Combustion 4-Cylinder Visible Working Engine w/Sound Plastic Model Kit (HM11US)

Haynes Internal Combustion 4-Cylinder Visible Working Engine with Sound Plastic Model Kit (HM11US)

Give your little mechanic the ultimate construction experience!

With over one-hundred precisely detailed pieces, all the tools you need, and exceptionally clear step-by-step instructions, it's easy to build a working model of a real car engine.

Screw in the screws, slide the pistons into the slots, fasten the casings, and stretch the belts over the gears.

The outer parts are fully transparent so kids can watch as the parts they built move together while illuminating spark plugs teach them how combustion makes an engine work.

Watch as the pistons turn, the gear spins, the belt rolls, and the big fan begins to twirl - it's a visual explanation of how an engine makes the wheels on a car turn!

It even plays an exciting engine sound whenever you press the button to turn it on.

Wrap your mind around one of the most influential inventions of the past 150 years with the Haynes Internal Combustion Engine - All you need is two batteries and little vegetable oil.
